Q: Why does the LED not match with my stock bulb when I'm trying to install it?

A: For the BMW F30, there are three bulbs located in the same housing: the bayonet 64132 bulb for parking, H7 halogen bulb or high beam, and
PW24W bulb for daytime running light. These bulbs are located in very close proximity, so there is a chance that you have pulled out the wrong bulb.

The PW24W daytime light is found at the bottom of the trio, so please double check the base to make sure your stock bulb matches with the new PW24W LED
daytime running light bulb.
